I To all whomdt may concern:

BENJAMIN F. WOODHOUSE, OF

MORRIS RUN, PENNSYLVANIA.

TRACE-FASTENER.

'No. 922,992. Specification of Letters Patent. Patented May 25, 1909.

Application filed February 24, 1909. Serial No. 479,782.

'Be it known that I, BENJAMIN F. D-

" nonsn, a citizen of the United States, and a resident of Morris Run,county of Tioga,

and State of Pennsylvania, have invented alcertain new and usefulTrace-Fastener, of

which. the followin is a s eoification.

s a The principal ob ect is to provide a comparatively simple andinexpensive trace fastener which may be applied with ease and facilityand which is positive in action and not l1 able to accidentaldisengagement.

To the end stated, the invention consists in the improvementshereinafter described and. claimed.

-=The nature, characteristic features and scope of the inventlon will bemore clearly understood from the following description taken inconnection with the accompanying drawing, forming a part hereof, andwhere 5 I Figure 1, is a perspective view of a trace fastener embodyingfeatures of my invention. Fig. 2, 1s a similar view with the i i the ofmy improved A, may be secured rigidly to the trace in the l generalplane thereof as in Figs. 2 and 4, or

i it may be pivotally attached as in Figs. 1

and 3. Said member A, is provided at one side With a longitudinallyranging channel orifgroove a, which merges into a trans- ,ver'selyranging slot (1, one wall (B, of the slotbeing substantially in obtuseangle in cross section, Figs?) and 4, and the other wall being inclinedand having an overhang, ledge or projection a The swingle tree member B,is L-shape, and one arm 6, is tapered or cone-shape and penetrates andfrictionally engages a correspondingly formed bore in the ferrule C ofthe swingle tree. The lockin element 5, extends in the general plane ofthe trace and is provided with a tongue or projection 6 which is a solidcounterpart of the slot or socket a, except that it has an undercutportion 6 to enable it to pass and then engage the abutment or wall aThere is also a rabbeted part 12", to engage the ledge or projection aFrom the foregoing it is manifest that to bring the parts intoengagement it is necessary to tilt them relatively to one another, andthat a pull on the trace acts simply to accelerate the locking of theparts.

Having described the nature and objects of the invention, what I claimas new and desire to secure by Letters Patent is A trace fastenercomprising interlocking members whereof one is channeled and slotted,the slot being provided with an overhang, ledge, or projection and withan angular abutment and whereof the other member is provided with arabbeted portion to engage said overhang and with an under cut tonguethat penetrates the slot and engages said abutment.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
